5pcs STM32F103C8T6 System Board SCM ARM DMA CRC Low Power Core Board STM32 Development Board Learning Board With Clock Reset And Power Management Function

Description: When the main chip STM32F103C8T6 development board is out of the factory, each block has written the test program in advance. When the power is on, the LED light will be uniformly blinking, so as to check whether the development board is working properly.
